Blazor Rest Api调用使用httpClient.GetJsonAsync错误

Question

我正在尝试使用以下调用从Blazor服务器应用程序调用Rest API以获取项目列表。API返回正确，但无法映射到项目对象，因为项目的JSON嵌套在结果属性下。

这是我打的电话

var projects = await httpClient.GetJsonAsync<Project[]>("projects");

这就是API调用的响应。

{
"message": "GET Request successful.",
"isError": false,
"result": [
{
"projectCode": "PRJ-1996",
"businessAssociateID": "BA000000000002",
"contractStartDate": "11/19/2020 8:37:17 AM",
"contractEndDate": "11/19/2020 8:37:17 AM",
"contractStatus": "Active",
"createdBy": "system",
"createdDate": "2020-11-19T08:37:17.37",
"active": true
},
{
"projectCode": "PRJ-1997",
"businessAssociateID": "BA000000000002",
"contractStartDate": "11/19/2020 8:37:17 AM",
"contractEndDate": "11/19/2020 8:37:17 AM",
"contractStatus": "Active",
"createdBy": "system",
"createdDate": "2020-11-19T08:37:17.37",
"active": true
},
{
"projectCode": "PRJ-1998",
"businessAssociateID": "BA000000000002",
"contractStartDate": "11/19/2020 8:37:17 AM",
"contractEndDate": "11/19/2020 8:37:17 AM",
"contractStatus": "Active",
"createdBy": "system",
"createdDate": "2020-11-19T08:37:17.37",
"active": true
},
{
]
}

如何使用GetJsonAsync函数映射到Projects列表。我看到的所有示例都只返回对象数组，而不返回响应消息。

这是我在电话中收到的错误。路由对于API调用是正确的，并且已经测试过。

JsonException: The JSON value could not be converted to Web.Data.Project[]. Path: $ | LineNumber: 0 | BytePositionInLine: 1.

Answer 1

是一种快速而简单的解决方案

class Response
{
public string  Message { get; set; }
public bool  IsError { get; set; }
public Project[] Result { get; set; }
}  

这也让您可以查看IsError和Message。
